Fig. 2 is a sectional view taken o-n the line .2 2 of Fig. l;

This invention relates generally to tanks and more particularly to car tanks having heating coils'arranged therein, and comprehends a means for distributing steam or other heating means to the coils. p

It is one object of this invention to provide 'heating coils arranged in sections in the tank with means for controlling the distribution of steam thereto whereby either section or both may be heated, as desired, and the heating of the sections regulated in accordance with existing conditions.

Another object of this invention is to pro-v vide a discharge nozzle for the tank which is arranged in series with a heat. distributor for coils arranged in the tank whereby the steam or other heating medium will first heat the nozzle and then be passed through the distributor and into the coil sections in the tank to heat the lading in the tank.

TheI tank shown in the drawings is desig' nated generally as A, and the bottom thereof is indicated at 1, the latter having coil sections 2 and 3 mounted thereon by suitable supports 4. Theinlet end of the coil section 2 is shown at 5 and the outlet end is shown at 6, while the inlet and outlet ends of section 3 are shown at 7 and 8 respectively.

Secured to the tank bottom 1 adjacent an opening 9 therein is a discharge nozzle. B which comprises a 'j aeketed casting having an inner wall 10 and an outer wall 11, the inner wall providing a passage for the discharge of the tank `lading 'and having its upper end threaded to accommodate the valve 12. The lower end of the discharge passage is normally closed by .a cap 13. j The casting is pro- 1927. Serial No.,189,319.

vided with an inlet pipe 14 to conduct steam into the jacket, and an outlet pipe 15 leads from the jacket as clearly shown at Fig. 2.

'A The bottom 1 has secured thereto adjacent an opening 16 thesteam distributor indicated generally at C, the same comprising a casting having a top 17 into which the inlet and outlet I ends ofcoil sections 2 and 3 extend. The castf ing issubstantially of hollow box-like construction and is subdivided into compartments by means of a central vertical partition 18 which defines section or compartment 19.

The other section or compartment defined by the partition 18 is provided with a horizontal partition 20 (see Fig. 2) and a vertical partition 21 (see Fig. 4), the partitions 20 and 21 thusdeining three chambers, 22, 23 and` 24 respectively, chamber 24 receiving steam from the outlet pipe 15 which leads thereto from the casting B. i

The partition 2() provides a bottom fo-r the chambers 22 and 23 and the bottom of cach of said chambers is provided with an opening in which is secured an annular ring 25 forming a seat for a` valve `26 mounted through the bot'v tomof the casting and provided with an operating rod 27 controlled by a hand wheel 28 `or the like.

v The chamber 24 provides a common inlet for admitting steam to either or both of the chambers 22 and 23, said chamber 24 extend- 'ing beneath both ofsaid chambers 22 and 23,

and the compartment 19 provides a common and asshown in Fig. 3, the casting C Vis positioned within the center sill or girder 30, the casting thus being protected, and the tank is anchored bybrackets 31 secured to a plate 32 carried by said center girder. The speeitic mounting means for the tank as shown in the drawings are merely illustrative, they forming no particular part ofthe invention, and the tank may be mounted on a car frame in any suitable manner.

will be apparent that steam passed through the inlet 14 into the discharge nozzle B will 105 With the construction just described, it

10 from the casting 'of casting' the v.valves '26 .controlling the admission lof steam into the chambers 22 and 23 may either or both be open' to permit'the steam to pass from the common inlet 24 into l5 either o'r'botli of the chambers 22 and 23 i whence it will pass into the coil sections 2 and Band pass from sa`id coil sections into the l compartment 19 and then out to the atmoslug 29 has been removed. It is apparent 'also thatl pher'e when the the amount of steam which passes into the. coil sections 2 and- 3 may" be varied by proper manipulation of the valves 26, 'thereby varying the temperature of the coil sections 15 2 and 3 as required.

What is claimed iss',

1-. In a car tank having series of continuous. heating coils therein, a distributor secured to the tank land having valve lcontrolled inlet chambers connectedv respectively to the inlet ends of the series of'coils, a steam inlet .y chamber common to said first named steamv outlet, a distributor secured to the tank provided with a steam outletcommon tof each ,series of coils, a valve controlled chaxriber to which the inlet end off'eachseries of coils is connected, and a common steamjnlet chamber for said valve controlled chambers. In witness whereof I have hereunto-set myhand. g Y
